| 摘 要： | 成岩作用研究表明，戴南组二段成岩作用类型主要有机械压实、胶结、交代、溶解、粘土矿物充填等，并进行了各成岩作用对孔隙改造规模的统计。成岩作用阶段的划分，采纳了中华人民共和国石油天然气行业标准，将戴南组二段划分为早成岩Ｂ期和晚成岩Ａ期两个阶段。次生孔隙的发育、分布与泥岩压实曲线的紧密压实、大量脱水阶段或有机质的成熟阶段、生油门限以及混层粘土的第一迅速转化带有着密切联系，从而成为次生孔隙预测的着眼点。

| Abstract: | Diagenesis study shows that the type of diagenesis in the second member of Dainan Formation in Qintong depression are mainly mechanical compaction,cementation,replacement,dissolution and clay mineral filling etc.The transform scale of pores by diagenesis have been statisted.The diagenesis stages are B stage in early diagenetic time and A stages in late diagenetic time.The develope and displibution of secondary pore have closely connection with densely compacting,massdehydration stage of the curve of mud compactjon,or the mature stage,oil generating window of organic matter and the first rapid inversion zone of mixed layer clay minerals,according to this we could predict secondery pores distribution. |
